$25-50 USD / hour

You have to maintain and extend an existing C#/WPF windows desktop application (~25k LoC). You are working with a local engineer, who does the final integration and testing. It's a software application for an industrial machine, including some screen for visualization, a 2D drawing tool, data management,... also refactoring of existing modules will be necessary. The software is already in the field. This mean we have to make sure, no new error will be introduced after an update - work precisely and conscientiously. Your availability should be around 30h/week for the next 12 months. We will accept a certain training period to get into the project, but you have to convince us right from the start.
